A facile synthesis of gem-difluorinated heterocyclic compounds using anodic fluorination of 2-cyano-1-methylpyrrole as a key step

Anodic fluorination of 2-cyano-1-methylpyrrole 1 using Et3N.5HF in an undivided cell provided 5,5-difluoro-1-methyl-3-pyrrolin-2-one (5a). The Diels-Alder reaction of 5a with various dienes was successfully carried out to provide gem-difluorinated heterocyclic compounds in excellent yields.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 96-54-8, in my other articles.

Theoretical investigation of protonated thiophene and two of its nitrile substituted derivatives (2-cyanothiophene and 3-cyanothiophene)

Theoretical and experimental spectroscopic data for protonated cyano-thiophenes (R-CNH+ with R = C4H3S), which are needed for their interstellar search and/or detection, are still lacking in the literature. Considering the high abundance and reactivity of H-3(+) in the interstellar medium (ISM), a quantum chemical investigation on protonated thiophene and two of its nitrile-substituted derivatives (2-cyanothiophene and 3-cyanothiophene) is undertaken for their characterization. The geometrical structures for the title species are calculated at the M06-2X/6-31G(d,p) level of theory, followed by an empirical correction for systematic errors. At the same level of theory, IR and Raman spectra are explored and the rotational parameters are calculated. The proton affinity (PA) of R-CN and the enthalpy, entropy and Gibbs free energy changes (Delta H-r, Delta S-r and Delta(r)G) of the reactions producing R-CNH+ are computed at the G2(MP2) and G3B3 levels of theory and at different temperatures. The PA calculations show that the protonation favors the nitrogen atom, while Delta H-r, Delta S-r, and Delta(r)G reveal the spontaneous reactions producing R-CNH+ and their neutral forms. In addition, quadrupole hyperfine structures are predicted, while the region where the brightest lines fall at different temperatures is discussed. These results are expected to assist astrophysicists and astrochemists in the search for new species in the ISM.

Poly(styrene)-co-2-vinylpyridine copolymer as a novel solid-phase adsorbent for determination of manganese and zinc in foods and vegetables by FAAS

The aim of this study is to extract zinc and manganese from foods and vegetables using an amphiphilic copolymer adsorbent, poly(styrene)-co-2-vinylpyridine which was synthesized via reversible addition fragmentation chain transfer (RAFT) polymerization from styrene and 2-vinyl pyridine in the presence of a trithiocarbonate and 2,2 ‘-azo-bis isobutyro nitrile (AIBN) in toluene solution under argon at 80 degrees C. Fourier Transform Infrared (FTIR) and proton nuclear magnetic resonance (H-1 NMR) spectroscopy were used in the characterization of the obtained copolymer. Under the optimum conditions, several validation variables such as uncertainty measurement, selectivity, robustness, precisions, matrix effects and accuracy were investigated. Taking an adsorption time of 15 min, detection limits of 0.04 mu g L-1 and 0.2 mu g L-1 and 7.9 mu g L-1 and enrichment factors of 145 and 110 were obtained for Mn(II) and Zn(II), respectively. The method was successfully applied to the analysis of Mn(II) and Zn(II) in foods and vegetables.

Synthesis of 3-methylthio-4-aryl-3-pyrroline-2,5-diones and 3-arylpyrolidine-2,5-diones by reaction of nitroketene dithioacetal with arylacetonitriles

The reaction of nitroketene dithioacetal (1a), i.e., 2,2-bis(methylthio)-1-nitroethylene, with arylacetonitriles (2a-I) in the presence of the base like sodium hydroxide gave 4-nitrobut-2-enenitriles (3a-I) which were converted into 5-hydroxyimino-4-methylthio-3-phenyl-3-pyrrolin-2-ones (4a-i) under refluxing in methanol. Title compounds (5a-i) were readily obtained by the treatment of 4a-i with hydrochloric acid and were finally led to N-methylated products (6a-I) with methyl iodide. The reduction of maleimides (4-6) with zinc dust in acetic acid afforded the corresponding 3-arylpyrrolidine-2,5-diones (7a-i) that can be converted to pharmacologycally active compounds like mesembrines.

Investigation of conjugated dinitrones – Derivatives of pyrroline oxide

The molecular structure of three derivatives of bis(2-R-5,5-dimethyl-3-oxo-1-oxide pyrrolin-1-ylidene-3), where R = CH3 (5a), C6H5 (5b), C(CH3)(3) (5c), and of the complex of 5b with copper(II) hexafluoroacetylacetonate [Cu(hfac)(2) (5b)] was investigated by X-ray diffraction analysis in the framework of our studies of the possible tautomeric equilibrium conjugated dinitrone nitroxide biradical. The pyrroline rings of the molecules under analysis are planar (rms deviations of atoms are no more than 0.041 Angstrom), and the interplanar angles are 32.01(5), 42.84(9), and 51.45(7)degrees for 5a, 5b, and 5c, respectively. It is established that the bond lengths of the C(2)-C(3)=C(3a)-C(2a) fragment are equalized to C(2)-C(3) 1.42 and C(3)-C(3a) 1.40 Angstrom. The N–>O bond lengths of the nitrone group are within 1.250(4)-1.282(4) Angstrom [in Cu(hfac)2 (5b)]. The geometrical data obtained do not permit us to make an unambiguous choice between the tautomeric structures. The magnetic susceptibility measurements of the Cu(hfac)2 solid complex (5b) and the absence of paramagnetism in solid compounds 5 indicate that they are diamagnetic.

ZG-1494 alpha, a novel platelet-activating factor acetyltransferase inhibitor from Penicilium rubrum, isolation, structure elucidation and biological activity

A novel inhibitor of platelet-activating factor (PAF) acetyltransferase, an essential enzyme in the remodeling pathway of platelet-activating factor synthesis, was identified by a high throughput screen of natural product extracts of microbial origin. The compound, ZG-1494 alpha, was isolated from an ethyl acetate extract of a culture broth of Penicillium rubrum through bioassay guided fractionation. The structure of ZG-1494 alpha was determined by spectroscopic methods. A key feature of the structure, which is relatively rare among natural products, is the 5-hydroxy-3-pyrrolin-2-one moiety. A C-13-C-13 INADEQUATE was utilized to unambiguously determine the regiochemistry of this molecule.

Volatile Organic Compounds (VOCs) of Endophytic Fungi Growing on Extracts of the Host, Horseradish (Armoracia rusticana)

The interaction between plant defensive metabolites and different plant-associated fungal species is of high interest to many disciplines. Volatile organic compounds (VOCs) are natural products that are easily evaporated under ambient conditions. They play a very important role in inter-species communication of microbes and their hosts. In this study, the VOCs produced by 43 different fungal isolates of endophytic and soil fungi during growth on horseradish root (Armoracia rusticana) extract or malt extract agar were examined, by using headspace-gas chromatography-mass spectrometry (headspace-GC-MS) and a high relative surface agar film as a medium. The proposed technique enabled sensitive detection of several typical VOCs (acetone, methyl acetate, methyl formate, ethyl acetate, methyl butanol isomers, styrene, beta-phellandrene), along with glucosinolate decomposition products, including allyl cyanide and allyl isothiocyanate and other sulfur-containing compounds-carbon disulfide, dimethyl sulfide. The VOC patterns of fungi belonging to Setophoma, Paraphoma, Plectosphaerella, Pyrenochaeta, Volutella, Cadophora, Notophoma, and Curvularia genera were described for the first time. The VOC pattern was significantly different among the isolates. The pattern was indicative of putative myrosinase activity for many tested isolates. On the other hand, endophytes and soil fungi as groups could not be separated by VOC pattern or intensity.
